摘要
系统采用基于单片机AT89S52的智能温度控制器。水温信号由DS18B20数字温度传感器采集,控制器采用数字增量式PID算法,控制信号经继电器实现对热电炉工作状态及水温控制。采用RS232串口与上位机通信,实现PC机的多个控制对象的集中监控。
System adoption according to the intelligence temperature isetrol of the single slab the machine AT89 S52 machine.The water temperature semaphore is spread a feeling machine by the DS18 B20 figure temperature to collect,the controller adopts the figure increment type PID algorithm,control signal through the relay realize is the thermal electric furnace operate status and the water temperature control.Adopt one RS232 string orifice and place of honor machine correspondence,carry out much concentration supervision that control object of PC machine.
